AUTOMATIC RELIEF DEVICE FOR S TEAM-RADIATORS.
Specification of Letters Patent.
PatentedFeb. s, 1916.
Application filed December 14, 1914. Serial No. 877,162.
To all whom it may concern:
Be it known that I, THoMAs F. DEXTER, citizen of the United States, residing at New Preston, in the county of Litchfield and State of Connecticut, have invented certain new and useful Improvements in Automatic Relief Devices for Steam-Radiators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to certain new and useful improvements in automatic relief devices for steam radiators.
My present invention is an improvement on the device shown and described in the Letters Patent issued to me, November 5, 1907, No. 869,884, wherein no provision was made for removing the accumulated sediment without removing the entire internal mechanism. In this, my present invention, I have fully overcome this objection and have greatly simplified and cheapened the construction and materially increased its efliciency by a less number of parts.
In the accompanying drawings illustrating my invention, Figure 1 represents a central sectional view of the casing and plugs and a broken view partly in section of the upper end of the air tube. Fig. 2 is a sectional view of the casing and air tube on line 22 of Fig. 1; and Fig. 3 is a bottom plan view of the casing and water outlet pipe on line 33 of Fig. 1.
The casing 1 is provided with the main inlet 2 and outlet 3, and screw plugs 1 and 5.
6 is the inlet chamber for water, air and vapor. 7 is the water outlet tube screwed into the lower wall of this chamber and communicating therewith. 8 is an air tube screwed into the upper wall of the chamber communicating in like manner with said chamber.
The water enters the chamber 6see arrows a-passes down the-tube 7 into the chamber 9 of the plug 5, thence up through the discharge passage 10 and out through the outlet 3. The dotted line 11 represents the normal water line, and the space above this line is for air and vapor, which, represented by arrows 6, passes up through the tube 8 I and out through the small vent 12, which vent is smaller than the bore of the tube below said vent, Fig. 1, into the chamber 13 of the plug 4c, thence down through the discharge passage 14 of the outlet 3. Y The continuously open vent l2 permits a free circulation of air or vapor from the chamber 6 into the discharge, thereby preventing siphoning action, and the tube 7 is of sufiicient capacity to provide a free outlet and prevent undue accumulation of the water.
The foreign matter carried by the water will naturally gravitate to the bottom of the chamber 9 of the plug 5, and such sediment can be readily removed by simply unscrewing said plug, and either tube can easily be removed by simply removing the plugs overlying said tubes. a.
From the foregoing, it will readily be seen that my improved device maintains the proper efiiciency with but few parts; is cheap to construct and easily kept in working condition.
Having thus described my invention, what I claim is: v 1. An automatic relief device comprising a casing having an inlet chamber projecting in the casing and an outlet, chambered plugs attached to the casing, a water outlet tube communicating with the inlet chamber and the chamber of one of said chambered plugs, an air tube communicating with the inlet chamber and the chamber of the other of said chambered plugs, said casing having passages communicating with the outlet and the chamber of said chambered plugs.
2. An automatic relief device comprising a casing having an inlet chamber projecting in the casing and an outlet in alinement with each other, chambered plugs attached to the casing on each side of the inlet chamber, a water outlet tube secured to the wall of the inlet chamber and communicating with said chamber and the chamber of one of the chambered plugs, an air tube secured to the wall of said inlet chamber and communicating with said chamber and the chamber of the other of said chambered plugs, said casing having passages communicating with the chambers of said chambered plugs and with the outlet.
In testimony whereof I affiX my signature in presence of two witnesses.
THOMAS F. DEXTER.
